2 Claims.

This invention relates to perforator and dispenser attachments to be applied to standard cans containing liquids to be dispensed therefrom.

An important object of our invention is to provide a device of the aforementioned character which has a piercing element provided with helically-shaped locking means to engage a can top after perforation, and secure the same in removably locking engagement therewith.

Another object of our invention is to provide an attachment of the aforementioned character having spout dispensing means similar to oil can construction.

Another object of our invention is to provide piercing means, and auxiliary piercing and looking means which will secure the invention removably to the top of a standard can.

Another object of our invention is to provide a device of the aforementioned character which will pierce a can and is also provided with force pump means in order to dispense the contents of the can by the auxiliary aid of air pressure.

Another object of our invention is to provide a device of the aforementioned character which will be easily and readily attachable to a standard can and which will be easily removable therefrom, yet will stay in a fixed relationship during the period of dispensing the contents from the said can, yet a device which is practical, efiicient, useful in its operation. and of such simple construction that it will lend itself to economical manufacture in quantity production.

Other features and objects of our invention will become apparent from the accompanying drawings and the ensuing description wherein like numerals are used to designate like parts and in which:

In general practice especially in machine shops and other similar establishments where oil has to be used to great extent for machining opera tions or for lubrication purposes, the conventional can shown in Figure 6 is utilized and is comprised of body 29 and spout 30 and a thread-, ed portion 3| which serves to secure the spout 30 to the body of the can removably so that it may be filled with oil.

The tendency in general practice, has been that these cans are dropped and caused to be broken and smashed from time to time from use and hence require replacement continually. These cans are comparatively expensive consid-'- ering the invention we have provided, and it is our intention to replace abuse of this type of oilcan structure by replacing it with our invention which is cheaper to manufacture and produce, and may be used interchangeably with cans of standard manufacture.

Another disadvantage, also, in the use of cans shown in Figure 6,.is that when a can is selected by a user, aiew squirts of oil usually have to be expelled therefrom, by forcing the bottom portion of the can or manipulating it so as to eject forcefully a few drops, so that the user may determine whether, it is the proper grade of oil. Considerable oil is thus wasted and hence lost.

Our invention, on the other hand, in being at tached to a standard can which is of rigid construction, will permit our use of the bottom portion of the can for manipulation to eject forcefully from the spout, oil which is necessary. The can utilized will always have imprinted thereon as it comes from the manufacturer, the imprinted matter carrying the grade of oil and the type of oh and the usesto which it may be applied. Therefore it will save. considerable .oil, which at the present time is used for purposes of inspection in order to determine whether the oil contained in a can of the type shown in Figure 6, is satisfactory oil needed for a particular operation.

Our method of dispensing oil from a unit such as we created will also enable a manufacturer to keep his product before the user at any and all times, which incidently is good business and good advertising. Ordinarily, cans of this type have to be pierced, the oil is then poured into standard oil cans such as shown in Figure 6, and soon the grade of the contents becomes unknown and its particular uses.

Referring now, particularly, to Figures 1, 2, 3, 4, and. 5, a preferred form of our invention is indicated. In those views the wing-nut member i3 is shown with a recess portion M in order to receive a gasket l5 which may be made of cork or of a type of rubber which is impervious to oil and which will not deteriorate when coming in contact with oil.

The wing-nut member Iii is provided with a counterbore I9 to which is secured a conventional oil spout H being of a tapered construction and having a tapered recess or opening l2 terminating in a fine spout so as to permit oil to be. ejected therefrom in minute quantities as lubrication conditions may necessitate. To the wing-nut member I3 is secured the blade member l6 which is provided with a pointed portion 24 and an enlarged portion in an upward direction provided with the off-set portions 25 and 26 creating the rib structure for reinforcing this blade so as to make it rather rigid for the perforating action which it has to perform. The upper portion of the blade I6 is provided with an opening 21 and terminates in two spiral portions I! which are provided with the bent portion 28 which. may be riveted or spot-welded to the inner recess [4 of the wing-nut member l3. The bore 19 after the gasket 15 is secured thereto leaves a resultant communicating recess :8 for the oil to pass thru to the spout recess l2.

The device may be grasped rigidly between the fingers and palm of the hand and forcefully brought to bear down on the top surface 19 of the oil 22 will be forcefully ejected from the spout opening l2.

We wish to stress the structural. function of the portions 11 which. are given the same pitch or lead and are equivalent in action to. what is known as a. double thread. The pitch of each portion I! being the same and being positioned a diametral distance permits the said portions to act simultaneously in effecting the sealing of the device against the top of a can.

The illegible written matter designated 34 indicates the writing on the label of the. can which will disclose to users after a cursory inspection the gradeof oil, the manufacturers name, and thus serve an advertising function as Well as an informational function in giving the user proper notice of the product about to be utilized.

Figures 7 and 8 show another form of our invention. as utilized with a larger type of can 33, and embraces theuse ofauxiliary pressure means for forcing the liquid contents of the can thru.

without inverting the can. The structure generally comprises two strap members 31 which are formed as indicated in order to take adjustably a series of varied diameters, and shapes of cans such as square, hexagonal, etc. These strap members are connected articulately at one point by the screw and a nut M and are secured to the pump unit 48 which is provided with the fork member 50, being further secured adjustably at the opposite ends by virtue of the screw 38 and the nut 39. It may be noted that the strap members 31 preferably possess a ribbing structure 61 so as to lend rigidity and thus make for a firm gripping of the can 33. The top of the can is seamed as at 35 and so is the bottom 36.

The liquid contents of the can are designated 66 and it may be noted that the piercing point 65 of the tube 64 reaches almost to the top of the can 33. The oil level is below the point 65 and being out of contact with the opening 68 will befedthru the opening 10 later to be described.

To elucidate further the structure comprising our invention, the forked member is secured articulately by virtue of the screw 49. The member 45 has an eye portion 46. The upper portion of the clamping unit is comprised of the member 44 having an anchoring point 42 and a handle portion 43 for conveniently carrying the assembled unit of our invention and a can once they are assembled in, place firmly together. The member 44 and the member 35 have right and left hand threads in order to match the right and left hand threaded portions 16 and ll of the turn buckle 75, which is provided in ordcr to take in odjustably various heights of cans.

The piercing unit 65 is encased. in a tapered housing 69 having an oil out-let H1. The combination of the unit 65 and 69 are properly and frictionally secured in the core opening, and bore, and counter-bore designated 81, connecting with the bore 88 and further connecting with the bore 6! in the casting 60 which has a female threaded extension 59, reinforced to the remaining portion of the casting 60 by virtue of rib 63. The upper portion of the casting is counterbored as at 89 in order to provide a proper retaining portion for the gasket member 14 which is to seal the unit with the can bottom 35 after it has once been pierced. Tho the turn buckle serves to hold this unit firmly and fixedly in assembly, yet it may be removed after the contents of the can have been completely dispensed.

The casting 66 is also provided with a boss H into which fits the reinforced end 12 of the flexible tubing 13 terminating in a suitable spout, the flexible tubing serving the purpose of convenient manipulation to portions of machinery and equipment that is not readily accessible to a rigid form of spout.

The pressure assembly is comprised of a pump housing 48 having a hub extension 49 in order to give proper guide to the piston plunger 5| having also a knurled knob 52 or other suitable manipulation knob. The plunger rod 5| is secured to a leather cup washer 53 which has thin side walls and which tends to flare out on a down ward stroke of the knob 52 yet tends to collapse on an upward stroke, to admit air to come thru into the passage 55 past the piston 53 when on the downward stroke, the side portions of the cup 53 spread out to forcefully compel the air to proceed thru the tube 58 and thru the opening 5! and then follow the arrows thru the outlet 63 accumulating pressure at the top causes the oil level oil to drain the tubing needed.

The tapered spring members 54 having smaller coils 47 the smallest being at the top and nesting within the leather cup piston 53 serves to return the plunger upwardly after it is once depressed in a downward direction. Several manipulations of this plunger will accumulate sufficient air pressure in the top of the can in order to dispense the liquid contents within the can. As the contents of the can are gradually dispensed, air automatically takes its place within the container, and therefor just a slight pressure is required to be built up within the can in order to forcefully eject the liquid therefrom.

The pressure casting 48 is secured to the tubing 58 by virtue of a flanged coupling 56, threaded at 62, secured to the casting 48, and having a reduced hub 51 which is irictionally secured to the tubing member 58. Altho, leather has been specified for the piston or cup 53, any other similar suitable material may be utilized for the purpose.

In Figures 9 and 10 we show a slightly modified form as compared to our invention depicted in Figures 1, 2, 3, 4 and 5. In this form we indicate a wing-nut member [3, having a recess 14 and a suitable gasket member 15 to secure to the top 19 of a can 26. To the lower portion of the wing-nut member I3 in a suitable counterbore is secured by a drive fit method a piercing member 78 having a pointed portion 86 for piercing a can and having a further counterbored portion at the top designated 84 and an oil connecting feed recess 85 which connects the recess l2 in the spout I i to the inner portion of the can.

The locking means utilized in this particular instance comprises the piercing blades 8! spotwelded to the wing-nut member It at the point 83, being helically shaped as at 8| the same as the portions I! of the form of invention illustrated in Figure 1, having a cam actuating and locking surface which will aid in looking removably this unit to the top portion of a can after it has been pierced.

The members 80 are provided with pointed portions 82 which pierce the can forming recesses 90 which when the wing-nut member is 65 to be forced downward and the "thru the opening '13 and out into 33 for actual application where turned one eighth or one quarter turn, will lock the entire unit in assembly. The gasket l5 being of sufficient resiliency to keep the assembly under tension until the contents of the can have been dispensed and it is desired to remove the unit to be applied to another can. The oil flows from the inner portion of the can thru the communicating recesses into the recess 84 and out thru the terminus of the recess l2 or the spout II.

We believe we have described in rather succinct terms the nature and operation of our invention and described and illustrated fully, preferred forms of our invention, and inasmuch as our invention is susceptible of many modifications, alterations, and improvements, we reserve the right to all such modifications, altera tions, and improvements that come within the spirit and scope of our invention, the accompanying drawings and within the purview of the foregoing description; our invention to be limited only by the appended claims.

Having thus disclosed and revealed our invention what we claim as new and desire to secure by Letters Patent is:

1. A device of the character described comprising, knob means, spout means secured to the said knob means, can slotting means secured to the said knob means, the said slotting means terminating in multiple thread helically-shaped cam locking and sealing means adapted to secure removably the said device to a can, and gasket means secured to the outer lower portion of said knob means.
